In the third quarter of 2025, interbank rates around the world showed a mix of volatility and tightening, shaped by diverging central bank policies, currency pressures, and shifting capital flows. In Hong Kong, rates whipsawed dramatically due to aggressive currency interventions by the HKMA to maintain the USD/HKD peg.
Liquidity injections in May pushed overnight HIBOR close to zero, but as the HKD weakened toward the soft end of its band, the central bank reversed course and drained liquidity. This tightening drove interbank rates across all maturities sharply higher.
Meanwhile, in Kenya, the Central Bank introduced KESONIA, a standardized overnight interbank rate. The rollout was smooth, with stable transaction volumes and minimal disruption to liquidity. This marked a positive step toward greater transparency and more efficient monetary policy transmission in the region.
In Vietnam, the interbank market faced pressures due to the depreciation of the Vietnamese d?ng. The State Bank of Vietnam took a cautious easing approach to support growth, but the widening interest rate gap with the U.S. dollar led to currency volatility. Reserve ratio cuts and looser lending policies provided short-term relief, though exchange rate concerns limited further easing.
Globally, major economies like the U.S. and UK approached monetary policy cautiously. The U.S. Federal Reserve signaled upcoming rate cuts amid a slowing labor market, while the Bank of England prepared to ease as inflation cooled. These moves influenced global funding costs, with carry trade activity and capital flows responding to shifting rate differentials.
